Limestone is very common in settings where wide, warm shallow seas once lay. It's generally made of microscopic particles of calcite, either the skeletons of tiny plankton or round grains called ooids, formed as calcite precipitates directly from seawater onto a seed particle as it does in the Bahamas today and other tropical sea islands. Here is a little of its variety.
